I do not know which would be more difficult, getting patients on chemo to run or obese Americans? Both are likely to soon die. (Sad but true)
At least the running for the mice was voluntary.
In the case of obese people, there is an argument that due to the high impact nature of running, other forms of exercise may be preferable (imagine the force of a heavy bodyweight crashing down on a person's joints many,many times over the course of a run, ouch). Perhaps cycling or swimming would be more advantageous to the overweight population. Of course, the benefits of walking are often understated, but certainly the humble stroll could impart a myriad of benefits to those of ill-health.
I wonder if the same health benefits can be had from involuntary running :P
